Hate speech is a negative form of communication directed towards an individual or a group of people. It is speech that offends a person's dignity. It aims to offend, belittle, hurt feelings and beliefs of another person or a group. In today's times, when the form of communication between people is globalized by various social networks and internet applications, we can say that it was never simpler and faster to spread a negative form of communication, in this case hate speech. The consequences of such communication can lead to violence that endangers the person towards whom the hate speech is directed. In this thesis we will talk about hate speech during the Covid-19 pandemic and try to discover new forms of hate speech, which are consumed through the social network Facebook. Through this paper, we will try to clarify the existence of a boundary between freedom of speech as a human right and hate speech as an unacceptable speech. It will also be shown how hate speech and freedom of speech are established through the legislative framework of the Republic of Croatia and the European Union. The empirical part of this paper includes examples of hate speech in Croatia during the time of Covid-19 pandemic, and with qualitative research, using the method of content analysis, we will investigate what forms of hate speech are present during the pandemic. We will investigate why readers reach for such a negative form of communication, which is not acceptable in democratic modern society.
